It has been reported that irradiation with Ultraviolet B can be used safely and effectively to treat vitamin D deficiency among vitamin D deficient patients. Exposure of the body in a bathing suit to 1 Minimum Erythemal Dose (MED) of sunlight is equivalent to ingesting about 10,000 IU to 25,000 IU of vitamin D. Thus, exposure of 6% to 10% of the body surface to 1 MED is equivalent to ingesting about 600 to 2500 IU of vitamin D. Although ultraviolet irradiation can be achieved from exposure to sunlight, it is generally available only seasonally and difficult for persons who are too ill to spend much time outdoors. Ultraviolet-Fluorescent lamp (KBD, Inc, Crescent Springs, Kentucky,USA) was designed to use ultraviolet B emitting fluorescent bulbs that have lower heat emission and allows a larger area of skin exposure. The Lamp is equipped with a timer for improved safety. This device is FDA (Food and Drug Administration) approved.
